Introduction About AMANTREL CAPSULE
AMANTREL CAPSULE contains Amantadine which belongs to the group of medicines called Dopamine agonists or Anti-viral agents. It is used in the management of Parkinson’s disease (a progressive nervous disease that causes tremor, muscular rigidity and slow imprecise movements), and manages various strains of influenza A virus (caused by the multiplication of the virus inside the body).
It is also used to manage shingles (herpes zoster) to reduce pain, which is a reactivation of chickenpox virus causing a painful rash and drug-induced extrapyramidal reactions (such as involuntary muscle contraction, tremors, stiff muscles, and involuntary facial movements caused by antipsychotics and other drugs).
Before taking AMANTREL CAPSULE inform your doctor if you have any problems related to kidney, liver or heart (which may cause shortness of breath or ankle swelling), any mental illness like schizophrenia (mental disorder) or dementia (memory loss) and glaucoma (increased pressure in the eyes).
AMANTREL CAPSULE is not recommended to be taken while you are pregnant or breast feeding. AMANTREL CAPSULE is not recommended for use in newborn and infants (below 1 year of age) and it should be used with caution in elderly patients (who are 65 years of age or older). Consult your doctor before taking this medicine.
The most common side effects of taking AMANTREL CAPSULE are loss of appetite, tiredness, dryness in the mouth, constipation and nausea or vomiting. Consult your doctor if any of the side effects worsen.

How AMANTREL CAPSULE Works
AMANTREL CAPSULE is a dopamine agonist and an anti-viral agent that manages Parkinson's disease and certain type of viral infections. As a dopamine agonist, it works by increasing the amount of dopamine, a chemical messenger in the brain which regulates the body movements. As an antiviral agent, it works against viruses to prevent their growth and multiplication. It also stops the viruses from releasing infectious chemicals (viral nucleic acid) to enter into the body which protects from influenza infection.
